title: Long-lived excited states in i-motif DNA studied by picosecond time-resolved IR spectroscopy.
abstract: The transient IR absorption spectrum for UV-excited i-motif DNA is reported for the first time and found to possess complex dynamics pointing to multiple decay processes, including possible charge transfer between packed hemi-protonated C bases.
